 337         Fixes for building on 64-bit hosts:
 338         * config/tc-avr.c (mod_index): New union to allow conversion
 339         between pointers and integers.
 340         (md_begin, avr_ldi_expression): Use it.
 341         * config/tc-i370.c (md_assemble): Add cast for argument to print
 342         statement.
 343         * config/tc-tic54x.c (subsym_substitute): Likewise.
 344         * config/tc-mn10200.c (md_assemble): Use a union to convert the
 345         opindex field of fr_cgen structure into a pointer so that it can
 346         be stored in a frag.
 347         * config/tc-mn10300.c (md_assemble): Likewise.
 348         * config/tc-frv.c (frv_debug_tomcat): Use %p to print pointer
 349         types.
 350         * config/tc-v850.c: Replace uses of (int) casts with correct
 351         types.
